I am using windows7, home premier, oem software. My disk drive has suddenly stopped reading disks. Drivers are all up to date. The disk tray opens ok, disk is inserted, lights are flashing as if reading, then lights stop. The disks are able to be read in both my laptop and another desktop running xp ok. Disk drive has previously burnt disks ok. There are no conflicts in device manager. Any suggestions would be welcome. Thank you.
